Somewhere in there I know there is an "I was wrong." We love you Mike!

And to the OP, sorry for the thread drift. Back to your kick ass 170!

As to Internet “data”, I’ve found that Airframes’ information is pretty accurate on items I’ve used. Desser....not so much.

They are double the weight, 16lbs vs 8lbs.

My Airhawks are 52lbs a side on my scale.

I’ve been flying with them on instead of my bushwheels this winter, they shake out there on the gear leg a LOT more. It was/still is a bit unnerving.

Are these buffed or stock?

ANY big tire will shake a lot on a Cessna gear. I’ve run a 185 with these tires and really didn’t care for them, mostly because where I was running them, they weren’t needed....working really solid gravel bars, etc.

But, I for one would never put a big Bushwheel on a Cessna gear either, unless I REALLY needed them, and if that were the case, I might start thinking about a different airplane.....but that’s me.

But—-worried about weight on Cessna gear, and consequent gear shake? Greg is going to have a shock when he gets those C-3200 wheel skis installed on his 180.

Try installing a set of C-3600 retractable wheel skis out there. Now, you’ve got 6 inch wheels, brakes calipers, (small) tires AND about 65 or so pounds of ski hanging on each gear leg. Now you’ll see some gear shake. And on skis, you’re beating the crap out of that gear. Ski flying is about as hard on the gear as anything out there.

I ran this setup all winter on a 185 for at least twelve winters, with no problems.

A fellow I know ran the same setup on an older 185 and had a gear leg break at the axle mount. After that, he had his gear dye penetrant tested every year before the skis went on. I think that was a bit of overkill, but having the gear checked every few years probably isn’t a bad idea with this much weight out there.

I also ran AWB 2500 wheel skis on my C-170B which had early 180 gear. Similar weights on those skis, and never broke anything, but gear shake? Oh yeah!

So, my point is, if you don’t really NEED those big tires, I sure wouldn’t run them. They no doubt cause stresses on the gear and gearboxes. But understand that these gears were tested by the manufacturer and in the field with significantly heavier loads out there, and in REALLY rough conditions, and frankly, gear breakages are pretty rare.
